SERIOUSLY gas'ing for one of these monsters.....would take a variety of modules. I've got a Mesa Single Rec v2 w/ KT77s, several pedals, and a bit of cash to make it happen.
Good luck those amps are pure beasts. Check out the randall forum, I think there are guys there who are selling some right now.

Good deals: rok-en-rol, truespin, ICFootball62, IndianScout, tinypants, HartRacer86, Huntred_67, Perandor, and many others from HC
